There are two main benefits for using a water filter with your bidet seat: (1) it’s better to use filtered water when cleaning your sensitive parts and, (2) it keeps the internal parts of your bidet seat free of sediment and impurities found in normal tap water.

Your bidet toilet seat works with a series of hoses, water reservoirs, and other parts where water runs through. For example, your bidet routes water from the tap and through the internal water heating system, then out the spray outlet found at the tip of the wash nozzle. It’s important to keep this system clean and free of mineral build-up, and a bidet water filter helps achieve that. A good comparison would be to look through an old pipe when a building is re-doing their plumbing. Mineral build-up can be seen all over the inside walls of the pipe, and you wouldn’t want the insides of your toilet bidet seat looking like that!

It goes without saying that there are definitely benefits of using clean, filtered water to clean yourself, particularly your private area. You wouldn’t want to expose one of the most sensitive parts of your body to particulates or bacteria. And when considering how easy and inexpensive these water filters are to install, there really isn’t a good reason to go without them.

Two types of bidet water filters are generally available, carbon filters and iodine filters. Carbon filters work because of a chemical process called adsorption. This is when the atomic charge of carbon frees particles and contaminants from their bond with water. As water passes thru the carbon filter, these particles chemically attach to the carbon, leaving clean filtered water to pass through.

Then there is the iodine filter. This type of filter works by adding a very small amount of iodine to the water as it passes thru the filter. This process sterilizes the water. Iodine is a common household item which is frequently used to treat scrapes and cuts. Iodine works for this purpose because it’s actually an antiseptic which kills bacteria. This concept is similar to how iodine water filters work for your bidet toilet seat.

Installing a bidet water filter takes just minutes. There’s a water outlet behind your toilet, which is connected to your bidet seat through a hose. This is the hose that supplies tap water to your bidet seat. Bidet water filters are designed to be attached to this hose, as they have one male end and one female end. To install, close the water shut-off on your water outlet. Then unscrew the hose which connects to the water outlet, and attach the female end of the water filter directly on to the outlet. Re-attach the hose to the other (male) end of the filter. Open the water-shut off valve, and then look around the area of your toilet bidet seat to ensure there are no leaks.

It’s recommended that you replace your bidet water filter every four to six months.
